Description

Technical Field

[0001] The utility model relates to a silkworm feed feeding technology, in particular to a material pressing mechanism and an intermittent feeding device. Background Art

[0002] Artificial feed for silkworms is mainly made of dozens of ingredients such as mulberry leaf powder, soybean powder, corn powder, etc. When using the powdered artificial feed, it is mixed with water in a certain proportion, shaped and packaged, and then steamed at high temperature to make mature feed blocks. When raising silkworms, the division and feeding of feed blocks are important links in the raising operation, and the manual operation method is labor-intensive, low in work efficiency, and cumbersome. Therefore, the development of supporting feed feeding equipment can effectively give play to the advantages of raising silkworms with artificial feed.

[0003] When cutting the feed block, the inventor weighed the cut feed after the feed was cut and found that the weight of the cut feed was different from the preset weight of the cut feed. After long-term research by the inventor, it was found that after the cutter cuts the feed block, the cutter and the cutting surface of the feed block have a large contact area. During the resetting process of the cutter, the feed block adheres to the cutter and is dragged by the cutter, which causes the cutting amount of the feed to change next time, thereby causing the cutting weight of the feed block to change. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art and provide a material pressing mechanism and an intermittent feeding device.

[0006] Optionally, the driving mechanism includes a driving member, a rotating member and a connecting member, the driving member is installed on the frame, and the power output end of the driving member is connected to the rotating member, and the driving member drives the rotating member to rotate coaxially, one end of the connecting member is eccentrically hinged on the rotating member, and the other end of the connecting member is hinged to the lifting frame, the driving member drives the rotating member to rotate, and during the rotation of the rotating member, the connecting member is driven to move up and down, thereby realizing the lifting of the lifting frame.

[0007] Optionally, an articulated seat is provided on the lifting frame, and the connecting piece is hinged to the articulated seat.

[0008] Optionally, a hinge shaft is provided on the rotating member, the hinge shaft is perpendicular to the circumferential surface on which the rotating member rotates, and a hinge hole is provided on the connecting member, and the hinge shaft is hinged in the hinge hole.

[0009] Optionally, a linear moving pair is also installed on the frame, the lifting frame is connected to the linear moving pair, and the lifting frame moves linearly under the action of the linear moving pair. The linear moving pair ensures the straightness of the movement of the lifting frame, thereby ensuring the stability of the pressing area of ​​the pressing piece, which makes it easier for the pressing piece to press the material.

[0010] Optionally, the linear motion pair includes a crossbeam, which is provided with a through hole for the connecting piece to pass through. The frame is a gantry, so there is a cavity between the top plate and the side plate of the frame, and the pressing piece is in the cavity. The driving mechanism is installed on the top plate of the gantry, and the crossbeam is installed across the frame, and the crossbeam is located below the gantry. A linear bearing is installed on the crossbeam, and a guide shaft is installed on the top of the lifting frame. The guide shaft and the linear bearing are slidably matched. The straightness of the movement of the lifting frame is guaranteed by the matching of the guide shaft and the linear bearing.

[0011] An intermittent feeding device includes a pressing mechanism, a conveying device and an intermittent feeding mechanism that drives the conveying device to feed intermittently. The driving mechanism of the pressing mechanism drives the intermittent feeding mechanism to work. When the pressing piece of the pressing mechanism presses the material of the conveying device, the conveying device stops conveying. When the pressing piece of the pressing mechanism is separated from the material of the conveying device, the intermittent feeding mechanism drives the conveying device to convey the material. Therefore, when the pressing piece is separated from the material, the intermittent feeding mechanism works, thereby driving the conveying device to convey the material forward for a stroke. When the pressing piece presses the material, the conveying device stops conveying, thereby ensuring that the relative position between the material and the pressing piece is stable when the pressing piece presses the material, thereby avoiding material damage caused by contact movement between the material and the pressing piece.

[0012] Optionally, the intermittent feeding mechanism includes an overrunning clutch and a first connecting rod, one end of the first connecting rod is equipped with an overrunning clutch, the overrunning clutch is mounted on the active roller of the conveying device, the other end of the first connecting rod is connected to a driving device, the driving device drives the first connecting rod to swing back and forth, when the driving device is working, the first connecting rod swings back and forth, and then the overrunning clutch drives the active roller to rotate intermittently, thereby realizing intermittent feeding of the conveying device.

[0013] Optionally, the driving device includes a transmission main shaft and a connecting rod mechanism. The transmission main shaft is rotatably installed on the frame, and rotating parts are installed at both ends of the transmission main shaft. The transmission main shaft is driven by the driving part, one end of the connecting rod mechanism is eccentrically hinged on the other rotating part, and the other end of the connecting rod structure is hinged to the first connecting rod. The intermittent feeding mechanism is driven by the same driving device. When the driving device is working, it drives the transmission main shaft to rotate, thereby driving the two rotating parts to rotate. One of the rotating parts drives the lifting frame to rise and fall under the action of the connecting part, and the other rotating part drives the first connecting rod to swing back and forth under the action of the connecting rod mechanism. Since the pressing piece presses the material by its own gravity, there is a time when the lifting frame moves downward and upward. The section makes the pressing piece and the lifting frame move asynchronously, and due to the overrunning clutch, the conveying device moves forward when the first connecting rod swings down, and the conveying device stops working when the first connecting rod swings up. Therefore, when the first connecting rod swings up, the pressing piece presses the material, and when the first connecting rod is about to swing to the upper stroke, the pressing piece moves up with the lifting rod, thereby causing the pressing piece to separate from the material. In other words, when the first connecting rod swings to the upper stroke, the pressing piece has already separated from the material. Similarly, when the first connecting rod starts to swing up, the pressing block starts to press the material. Since the lifting frame and the first connecting rod work continuously, the continuity of the intermittent feeding device can be ensured by adjusting the length of the sliding piece.

[0014] Optionally, the connecting rod mechanism includes a second connecting rod, a third connecting rod and a lever, the lever is rotatably mounted on the frame, one end of the lever is hinged to the second connecting rod, and the other end of the lever is hinged to the third connecting rod. Through the lever, the second connecting rod and the third connecting rod, the swing amplitude of the first connecting rod can be adjusted, thereby controlling the feed amount of the conveying device.

[0015] The utility model has the following advantages:

[0016] 1. The material pressing mechanism of the utility model uses the self-weight of the material pressing piece to press the material, and then the material pressing piece can be weighted, so as to ensure that the material is pressed without causing damage to the material;

[0017] 2. The material pressing mechanism of the utility model is provided with a sliding member, so that when the lifting frame is not in contact with the limiting part, the material pressing member and the lifting frame can slide relative to each other, and when the lifting frame is in contact with the limiting part, the material pressing member can be lifted and lowered synchronously with the lifting frame, so that during the lifting process of the lifting frame, the material pressing member has two positions: pressing the material and separating from the material, so that when the material is cut, the material pressing member can press the material, so that the material cannot move, thereby ensuring the cutting quality of the material;

[0018] 3. The intermittent feeding device of the utility model realizes the intermittent feeding of materials. When the pressing piece presses the material, the material feeding stops, and when the pressing piece separates from the material, the material feeding is realized, thereby providing a guarantee for the continuous cutting of the material.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 2 As shown, an intermittent feeding device includes a pressing mechanism, and also includes a conveying device 16 and an intermittent feeding mechanism that drives the conveying device 16 to feed intermittently. The driving mechanism of the pressing mechanism drives the intermittent feeding mechanism to work. When the pressing piece 1 of the pressing mechanism presses the material of the conveying device 16, the conveying device 16 stops conveying. When the pressing piece 1 of the pressing mechanism is separated from the material of the conveying device 16, the intermittent feeding mechanism drives the conveying device 16 to convey the material. Therefore, when the pressing piece 1 is separated from the material, the intermittent feeding mechanism works, thereby driving the conveying device 16 to convey the material forward a stroke, and when the pressing piece 1 presses the material, the conveying device 16 stops conveying, thereby ensuring that the relative position between the material and the pressing piece 1 is stable when the pressing piece 1 presses the material, thereby avoiding material damage caused by contact movement between the material and the pressing piece 1.

[0029] like Figure 1As shown, in this embodiment, the pressing mechanism includes a lifting frame 3, a driving mechanism and a frame 8, the driving mechanism is installed on the frame 8, and the driving mechanism drives the lifting frame 3 to rise and fall relative to the frame 8, a sliding member 2 is installed on the lifting frame 3, and the sliding member 2 can slide relative to the lifting direction of the lifting frame 3, one end of the sliding member 2 is provided with a limiting portion 4 that cannot pass through the lifting frame 3, the other end of the sliding member 2 passes through the lifting frame 3, and a pressing member 1 is installed on the sliding member 2 passing through the lifting frame 3, when the lifting frame 3 is in the down stroke, the limiting portion 4 is located above the lifting frame 3, this When the lifting frame 3 is in the upward process, the pressing piece 1 presses the material by its own weight. When the lifting frame 3 is not in contact with the limiting part 4, the pressing piece 1 still presses the material by its own weight. When the lifting frame 3 is in contact with the limiting part 4, as the lifting frame 3 rises, the pressing piece 1 rises with the lifting frame 3 and then separates from the material. Therefore, the pressing mechanism presses the material by its own weight. Therefore, the pressing piece 1 can be weighted according to the actual situation to ensure that the material is pressed without causing damage to the material.

[0030] In this embodiment, if Figure 1 and Figure 2 As shown, the transverse span of the material is relatively wide, and a plurality of sliding members 2 are installed on the lifting frame 3. The plurality of sliding members 2 are distributed at intervals in the transverse direction. For the convenience of processing, the spacing between two adjacent sliding members 2 is the same. Since a plurality of sliding members 2 are provided, the circumferential rotation of the pressing member 1 relative to the lifting frame 3 can be avoided. Therefore, in this embodiment, the sliding member 2 can be configured as a cylinder or a polygonal cylinder. Preferably, the sliding member 2 is a cylinder. In other embodiments, if the transverse span of the material is relatively narrow, the sliding member 2 can also be configured as one. At this time, in order to avoid the circumferential rotation of the pressing member 1 and the lifting frame 3, the sliding member 2 can be configured as a polygonal cylinder.

[0031] In this embodiment, if Figure 1As shown, in order to realize linkage with the intermittent feeding mechanism, the driving mechanism includes a driving member 7, a rotating member 6 and a connecting member 5. The driving member 7 is installed on the frame 8, and the power output end of the driving member 7 is connected to the rotating member 6, and the driving member 7 drives the rotating member 6 to rotate coaxially. One end of the connecting member 5 is eccentrically hinged to the rotating member 6, and the other end of the connecting member 5 is hinged to the lifting frame 3. The driving member 7 drives the rotating member 6 to rotate. During the rotation process, the rotating member 6 drives the connecting member 5 to move up and down, thereby realizing the lifting of the lifting frame 3. Optionally, the lifting frame 3 is provided with a hinge seat. The connecting member 5 is hinged to the hinge seat. Furthermore, a hinge shaft is provided on the rotating member 6, and the hinge shaft is perpendicular to the circumferential surface on which the rotating member 6 rotates. A hinge hole is opened on the connecting member 5, and the hinge shaft is hinged in the hinge hole. Optionally, the driving member 7 is a driving motor, and the power output end of the driving motor drives the rotating member 6 to rotate. In other embodiments, when the driving mechanism is not linked with the intermittent feeding mechanism, the driving mechanism can also use a lifting cylinder to directly drive the lifting frame 3 to lift, and the lifting cylinder can be installed on the frame 8, and the piston rod of the lifting cylinder is directly connected to the lifting frame 3.

[0032] In this embodiment, if Figure 1 As shown, a linear motion pair is also installed on the frame 8, the lifting frame 3 is connected to the linear motion pair, and the lifting frame 3 moves linearly under the action of the linear motion pair, and the linear motion pair is used to ensure the straightness of the movement of the lifting frame 3, thereby ensuring the stability of the pressing area of ​​the pressing piece 1, and making it easier for the pressing piece 1 to press the material.

[0033] In this embodiment, if Figure 1 As shown, the linear motion pair includes a crossbeam 13, on which a through hole for the connecting member 5 to pass is opened. The frame 8 is a gantry frame, so there is a cavity between the top plate and the side plate of the frame 8, and the pressing piece 1 is in the cavity. The driving mechanism is installed on the top plate of the gantry frame, and the crossbeam 13 is installed across the frame 8, and the crossbeam 13 is located below the gantry frame. A linear bearing 15 is installed on the crossbeam 13, and a guide shaft 14 is installed on the top of the lifting frame 3. The guide shaft 14 and the linear bearing 15 are slidably matched. The cooperation between the guide shaft 14 and the linear bearing 15 ensures the straightness of the movement of the lifting frame 3. In other embodiments, the linear motion pair can also use a linear slider and a linear slide rail. Optionally, the linear slide rail is installed on the inner side of the side plate of the frame 8, and the linear slider is installed on the lifting frame 3. The linear slide rail can also be installed on the outer side of the crossbeam 13, and the linear slider is installed on the lifting frame 3, and then the linear slider and the linear slide rail are slidably matched.

[0034] In this embodiment, if Figure 1As shown, the intermittent feeding mechanism includes an overrunning clutch 10 and a first connecting rod 11. The overrunning clutch 10 can be selected as a ratchet overrunning clutch 10 or a roller overrunning clutch 10. The overrunning clutch 10 is installed at one end of the first connecting rod 11. The overrunning clutch 10 is sleeved on the active roller of the conveying device 16. The other end of the first connecting rod 11 is connected to a driving device, and the driving device drives the first connecting rod 11 to swing back and forth. When the driving device is working, the first connecting rod 11 swings back and forth, and then the overrunning clutch 10 drives the active roller to rotate intermittently, thereby realizing intermittent feeding of the conveying device 16. In this embodiment, the driving device includes a transmission main shaft 9 And connecting rod mechanism 12, the transmission main shaft 9 is rotatably installed on the frame 8, and the two ends of the transmission main shaft 9 are installed with rotating parts 6, the transmission main shaft 9 is driven by the driving member 7, one end of the connecting rod mechanism 12 is eccentrically hinged on the other rotating part 6, and the other end of the connecting rod structure is hinged to the first connecting rod 11. In this embodiment, the intermittent feeding mechanism is driven by the same driving device. When the driving device is working, it drives the transmission main shaft 9 to rotate, thereby driving the two rotating parts 6 to rotate, one of which drives the lifting frame 3 to rise and fall under the action of the connecting member 5, and the other rotating part 6 drives the first connecting rod 11 to swing back and forth under the action of the connecting rod mechanism 12, and the driving device A driving motor is used, and a chain drive or a gear drive can be used between the driving motor and the transmission main shaft 9. In the present embodiment, a chain drive can be used between the driving motor and the transmission main shaft 9, that is, a chain plate is installed on the transmission main shaft 9, and the chain plate is located between the two rotating members 6. Preferably, the rotating member 6 is a rotating wheel, and a chain plate is also installed at the output end of the driving motor. Then, the two chain plates are driven by a chain. Since the pressing member 1 presses the material by its own gravity, there is a time period during the downward and upward movement of the lifting frame 3 so that the pressing member 1 and the lifting frame 3 do not move synchronously. Since an overrunning clutch 10 is provided, the first connecting rod 11 is lowered. , the conveying device 16 moves forward, and when the first connecting rod 11 swings up, the conveying device 16 stops working. Therefore, when the first connecting rod 11 swings up, the pressing piece 1 presses the material, and when the first connecting rod 11 is about to swing to the upper stroke, the pressing piece 1 moves up with the lifting rod, thereby making the pressing piece 1 separate from the material. In other words, when the first connecting rod 11 swings to the upper stroke, the pressing piece 1 has been separated from the material. Similarly, when the first connecting rod 11 starts to swing up, the pressing block starts to press the material. Since the lifting frame 3 and the first connecting rod 11 work continuously, the continuity of the intermittent feeding device is ensured by adjusting the length of the sliding member 2.

[0035] In other embodiments, the driving device of the intermittent feeding mechanism may not use the same driving device as the driving mechanism of the lifting mechanism. Therefore, the driving device of the intermittent feeding mechanism works independently and only needs to drive the first connecting rod 11 to swing back and forth. The method of driving the first connecting rod 11 to swing may adopt a crank rocker mechanism, a double crank mechanism, a double rocker mechanism and a hinged four-bar mechanism, etc. Of course, the connecting rod mechanism 12 of this embodiment may also be directly selected.

[0036] In this embodiment, if Figure 1 As shown, the connecting rod mechanism 12 includes a second connecting rod 121, a third connecting rod 123 and a lever 122. The lever 122 is rotatably mounted on the frame 8. A hinge shaft can be set on the outer side wall of the side plate of the frame 8, and then a hinge hole hinged to the hinge shaft is opened on the rod 122. Preferably, a bearing can be installed in the hinge hole, and the bearing sleeve is on the hinge shaft. One end of the lever 122 is hinged to the second connecting rod 121, and the other end of the lever 122 is hinged to the third connecting rod 123. Through the lever 122, the second connecting rod 121 and the third connecting rod 123, the swing amplitude of the first connecting rod 11 can be adjusted, thereby controlling the feed amount of the conveying device 16. Furthermore, a plurality of hinge holes are opened on the first connecting rod 11, and the second connecting rod 121 is hinged to different hinge holes, thereby changing the length of the first connecting rod 11, thereby changing the swing amplitude of the first connecting rod 11, thereby controlling the feed amount of the conveying device 16.

[0037] The working process of the utility model is as follows: taking the conveying of feed blocks as an example, the working process of the intermittent feeding device is explained, the driving motor works, and through power transmission, the transmission main shaft 9 rotates, thereby driving the two rotating wheels to rotate, one of which makes the lifting frame 3 rise and fall through the hinged connecting piece 5, and the other rotating wheel makes the first connecting rod 11 swing back and forth through the connecting rod mechanism 12, when the first connecting rod 11 is in the process of swinging up, the pressing piece 1 presses the feed block, and when the first connecting rod 11 is about to swing to the upper stroke, the pressing piece 1 moves up with the lifting rod, thereby making the pressing piece 1 separate from the feed block, that is, when the first connecting rod 11 swings to the upper stroke, at this time, the pressing piece 1 has been separated from the feed block, similarly, when the first connecting rod 11 starts to swing up, the pressing block starts to press the feed block, thereby realizing intermittent feeding of the feed block, and making the feed block be pressed by the pressing block when not feeding, thereby facilitating the cutting of the feed block.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
